DRAFT-CONTROLLING THROTTLE MEANS.

Specification of Letters Patent.

Patented Nov. 17 ,19141.

npplicatidn filed August 21, 191a. Serial in. 786,003.

This invention relates to an improvement in draft appliances for controlling the throttle or controlling member of asource of draft power so that when the device is ap lied to a series of implements 511th as p owe, the source of draft power it will be automatically shut ofi upon arrest of advancing movement of any one of the plows by contact thereof with a stump or a large stone, so as to prevent brea age which might otherwise occur. j 2 0 The device of my invention is especially applicable where more than one plow is employed in connection with a traction engine or other source of draft power, and it is one of the objects of my invention to 2'5 yieldingly or extensibly connect the several plows with the engine and to provide a single movable structure which is operatively connected with the controlling memher or throttle, and which is provided with 80 an independent connection with each implement or plow so that upon arrest of ad- Vance of any one of the plews the throttle or controlling member Wlll be operated to stop the engine.

Other features of novelty will be more fully described in connection with the accompanying drawings and will be more fully pointed out in and by the appended claims.

In the drawin :-Fig'ure 1 is a veiw in side elevation o the device of my invention as applied to a gang plow and an engine. ig. 2 is a I lac view of a movable or slidable co'ntroll 'ng means adapted for connection with the several plows and with the throttle. Fig. 3 is a sectional view thereof on line 3-3 of 2. ,Fig. '4 if a fragmental perspective portions in sections. Fig. 5 is a vertical longitudinal sectional view showing one form of extensible or yielding cennection for one of the plows. Fig. 6 is a horizontal view of such connection with the outer part thereof omitted. w

615 'Mi'flfit designate $6 Like characters similar parts throughout the different figarcs of the drawings.

As illustrated, 1 designates the rear end of a source of draft ower which may be a traction engine, and it is provided with a controlling member or throttle 2. The controlling member or throttle 2 is pivoted at 3 and may control the throttle valve by means of 1a throttle rod 4. A throttle controlling lever 5 is pivotally mounted at 6 on an extension 7 of the engine, and the upper end of the lever 5 may be connected with the throttle 2 by means of a bifurcated terminal 8. The extension support 7 is provided with pendant hangers 9 which serve as sup orts for grooved guides 10. A frame, in icated at 11, as a whole, is slidable in said guides 10 and sai' frame may consist of front and rear tn. verse frame members 12 and 13, respectively, and lateral members It which are adapted to slide in the grooved ways of guides 10.

In order to render the sliding means or frame more rigid, the front and rear transverse members 12 and 13 are connected by a plurality of rods 15. A yoke 16, connected with the front transverse member- 12 is provided with a plurality of apertures 17 for connection therewith of the lower end 18 of the throttle controlling 95 member 5. It will thus be seen that any movement of the throttle 2 will impart movement td the sliding r'neans or frame 11, and likewise, any movement of the sliding means or frame 11 will impart movement to the throttle 2.

In the present construction, I provide a truck for supporting the front ends of the glow beams and the truck is mounted upon eating wheels 19 and includes an axle 20, and a truck frame 21. A connection such as a clevis device 22 serves to rigidly or inextensibiy' connect the plow truck with the engine a inn relative movement therebetween in directions away from each other. "4'00 Pl'ows 22 and 23, having plow beams 24 and 25., respectively, are disposed in the rear of the plow truck, as is clearly shown in Fi 1, and the plow truck carries a plurality of devices for yieldin tion with the plow beams of the p ows. As shown, a casing 26, for each plow, is pro- Vided with e; pted to be pivotally supported on a rod 28 suspended from the plow" trees. As each yielding device is connec- 0.

e I .3. mo e similer in construction end cperction, only one be described in detail.

the front end of the plow bee-m Ed is disposed longitndinelly in the ,co.sing -26- end is provided on its forward end with spring 30 is provided at the rear of said casing 2d en. enpcneively ecting opting 31 is interposed between seid shoulder end abutmentto normelly wet to hold the parts in the position shown in lFiv 5, the spripgyielding under the loed imposed by "notion of eech plow, there .bei tour plows con- "templeted forensic shown nh tg g in to construction, are

llt will beeeen thet the s rings 31 hove it lost motion connection wit the rods 35 so thet it enyone of the lows should etrilre o, root orsm ell stone on be slightly retarddid ed orerrested. with respect to the other plowe, momenterily, ouch errest of movement will not be euficient toclose. the throttle beceuseot the slot 3%. ldowever, if any one of the plows should meet with en obstruction that would ceuse an ebruptly complete errest of advancing movement, then the springof the plow would ectucte rod 35 and close the throttle. By reeson of the loose connection of the'hoolred forward ends of the rods 35 with the transverse member 18, it will be seen that cny one of the rods 35 con drew the framell rear-weirdly while the remaining. rods 35 will freely elide on the member 13 and u permit rearward movement thereof, it being understood that any appreciable backward movement of the rods 35 would slide the frame it reerwerdly. lit will also be undcrstood that there will be emple lost motionin the connections so es to prevent closing of the throttle under any slight or temporary erreet of one low with res ect to enother. While ll believe that the evice of my invention ie beet adopted ornse' in connec" l tion with more than one plow, still, its

cdetptebility to one plow willbe cleor, end

will be seen that by conetructing and errenging the ports as hes been hereinbelore set forth so that each plow has n spring mozmted to coiiperete therewith, the structure is made more sensitive then would be possible were e m'ngle spring connected in the draft yoke or at the main drelft as at 16. it will be seen thet l have provided independent yielding devic'ee for connecting vided means independently connected ebutmentor pin 29.. A ehonlder eech plow with on engine, there bein prowith each plow, and with the controlling member or throttle of the engine'to-iclose the latter upon arrest or advance of any one of the plows. a
